Wow, surprising, it isn't sweet. I was imagining something juicy like Cactus Cooler but its dry, almost salty. The grapefruit citrus is bitter on the tongue. But then the aftertaste of aspartame & saccharine kicks in & it tastes kind of gooey & overly sweet. I don't care for the fake sweetener flavors.

Now that my tongue is more accustomed to the grapefruit taste, the pineapple flavor is more apparent. It's not especially exciting as a drink, a rather mellow beverage.
